One thing I have been researching and practicing is strobe lighting (and continuous lighting as well) for use with infrared studio photography. I have not done a tone of actual shooting, but the first thing I have noticed so far is that light fall of is much sharper when using ordinary flashes for IR studio shots. The flashes themselves output a surprising amount of IR light, but their coverage is a lot more narrow. I dont really know what causes this yet, but will continue to experiment and learn what I can.
I think Minolta Rokkor lenses look really cool in IR because they have a silvery look, the two photos below were both taken with an infrared converted NEX-5 using a Rokkor 35mm lens. Both shots required quite a bit of post processing to get them to look reasonably nice, this was mostly due to the heavy light fall off toward the edges of where the flash was pointed.
